Maxim,
Finally I managed to launch openmeetings with kurento and coturn. The
problem was in coturn server which didn't work as expected. I
installed coturn server on my private laptop (no firewall and NAT)
which listens on port 443, with the following configuration:
listening-port=443
tls-listening-port=5349
verbose
lt-cred-mech
user=kurento:kurento
realm=my_openmeetings_server_domain
log-file=/var/log/turnserver/turn.log
After that all openmeetings users can see each other cameras and hear
each other. The only problem remain, that session recording files are
wav file, not avi. Do you have a clue what is the reason is? Coul it
be a ffmpeg issue?
Best,
Yarema
